' A DING-MACHINE.

Specification of Letters iatent.

' Patented Sept. s, 1908.

Application filed January 15, 1906. semi N... 296,190.

To all whom it may-concern:

Be it known that I, JEssE G. VINCENT, a

citizen of the United States, residing at Detroit, in" the county of INayne and 'State of Michigan, have invented certain new and useful Improvements in Adding-Machines, of

which the following is a specification.

My invention relates to adding machines of that class adapted to print and list individual items and. to accumulate the total thereof and also to print such total or accumulation at the will of the operator and my invention concerns that particular type of such adding machines commonly referred to,

- or at one particular point in the accountant work'and the total or totals in another section or'.sections of the machine may be taken ofprinted at another time or any other place intthe accountant work. i

Theclass of machines to which my invention is particularly applicable is exemplified by the well known Burroughs. adding machine constructed and operating in substantial accordance with Burroughs patents, Nos. 504,963 and 505,078, issued on September 12, 1903, and for convenience in illustration and description of my invention I have shown the same incorporated therein, although, as will be understood, my invention is not limited to this particular application thereof, inasmuch as the same may be used in adding machines of the same generalcharacter and used for the same general purposes.

In the drawings Figure 1' is an elevation of the left hand side of a Burroughs machine illustrating certain parts which are'more or less directly concerned in the description of my invention; Fig. 2 a detail view of the upper forward part of the machine with my improvements incorporated therewith; Fig. 3 a perspective of certain of the parts constituting my im rovements; Fig. 4 a sectional elevation of t 1e machine on line 44 of Fig. 1; Fig. 5 a sectional elevation on the line 55 of Fig. 1; Fig. 6 a lan view of a por tion of the printing me c anism illustrating the splitting of the machine at a point hetween the fifth and sixth denominations mounting from the right hand, side of the machine. I

Inasmuch as the Burroughs machine is so well known and is also described in the Burroughs patents aforesaid, only those parts thereof which are directly concerned and cooperate with the devices constituting my improvements or attachments, xneed be described or referred to in detail.

The Burroughs machine is provided with a plurality of rows of keys 291 representing different denominations increasing from right to left, the keys in each row representing the digits 1 to 9. The capacity of the machine is of course increased by increasing the number of the denominations but in the present instance the machine is shown as provided with nine rows of keys, with the result that the trains of mechanism are in series of nine, Figs. 4, 5 and 6.

As is well known, the Burroughs machine is provided with a series of main levers or sectors 611, .mounted to' oscillate upon a main cross shaft 600 and correspondlng in number to the number. of the denominations represented on the keyboard. Each sector 611 carries at its forward end a rack 610 and at its rearward end a series of movable type plates 618, each plate bearing two type and the entire series of type representing the figures 0 to 9. Each rack 610 operates in a vertical plane between the two plates 210 and the same is normally held in its elevated position by means of its retainer 415, Fig. 1, itbeing understood that each one of theseries of racks is provided with its own independent retainer. VVhen an item is set up on the keyboard the retainer or retainers corresponding to the rows or denominations,

in which keys have been set or' depressed are swung in a clockwise direction, Fig. 1, by the contact therewith of the lugs 214* at the a ends of those sliding'bars or strips 214 corresponding with such operated keys, with the result that such retainers are swung rearwardly as to their lower ends and the corresponding racks are permitted to descend.

(upon the operation of'the machine) distances corresponding with. the value 'of the operated keys. a

The accumulating pinions 916 of a Burroughs machineare mounted in a swinging.

frame 910 arranged to rock upon the axis 900, whereby such pinions, which correspond in number with the racks, are adapted to be rocked into and out of mesh with their racks at the proper times. This rocking or swinging movement of the accumulating pinions is under the control of the pitman 914, whoseforward end is bifurcated and adapted to cooperate with the rocking frame in the usual and well known manner and whoserearward end is ioperatively connected with. thethreearmed lever 913, which is in turn rocked by a sub-total, the usual operation of the pitman. 914 is interfered with and to. this end a total the main rocking lever 813, through the medium of the wipe plate 821. For the purose of taking a total, either a grand total or key is provided 'on the keyboard and is connected by a link with the pitman. In the operation of printing and accumulating items the adding wheel pinions, which are normally J11 mesh with their racks, are swung out of mesh or engagement with their racks upon the initial movement of the operating handle or main shaft of the machine, whereuponthose racks corresponding to the operated keys descend freely distances corresponding with the values represented by the operated keys. After the item has been prin'tedand just before the racks begin their ascent upon the return movement of the operating handle or main shaft ofthe machine, the accumulating pinions are swung rearwardly into mesh with their racks so that upon the ascent of the latter the amount is transferred to the pinions.

In-the operation of taking a total, the total 'key is depressed'and'the forward end'of the pitman' 914 is held in a depressed condition through the medium of the substantially vertical link 911', with the'result that the accu-' mulating pinions, instead of being swung out of mesh with their racks upon the initial movement of the operating handle or main shaft, are left in their normal position of engagement therewith, so that the racks will' descend distances determined by the accumulation on said pinions and the amount of the accumulation will be printed. If the nominations.

the total. If, however, a sub-total is to be taken, the total key is released and permitted to ascend at the end ofthe forward stroke of the operating handle, with theresult that'the pitman 914 will be returnedlto its normal position and the accumulating the accumulation which had been; transferred to. them by the accumulating pinions.

. In the usual Burroughs machine the retainers 415 are simultaneously rocked rearwardly as to their lower ends and the racks 610 thereby unlocked by a universal rod marked 209 in said Burroughs, Patent No.

504,963,. which -rod is under the control of the total key connections. As shown in said last named Burroughs patent and as is the c se in the-usual Burroughs machine, the total key 265 is connected with a bell crank 227, which is secured to a transverse rock pinions will be left in" mesh with theirracks which, in their ascent, will re-transfer'thereto shaft 204 carrying at the other or right hand side of the'machi'ne a depending arm somewhat similar to the bell crank 227. This bell crank 227 and the similar arm on the other side of the machine are connected by parallel links 216, with the opposite ends of said' universal rod 209. It will be understood that when the total key of the usual- Burroughs machine is depressed the said universal rod is by that act drawn rearwardly and all of the retainers 415 from side The manner of splitting a Burroughs machine is now well known in the art, but for the purpose of a clear understanding thereof in this specification, I have, in Fig. 6, illustrated a portion of the printing mechanism of such machine which has been so modified as to cause a' spiltting of the machine, in

the present instance at a point or along the line between the fifth and sixth denominations countingfrom the right hand side of the keyboard, with the result that the. machine will be dividedinto two sections, the right hand section having, in the present instance, a capacity of five denominations and the left hand section a capacity of four de- However, it will be understood that the number of the denominations in the machine is optional and also that the number thereof in one or the other sections or the relative number thereof in the difi'crent sections is likewise optional. Furthermore, the machine may be split at a 897,941 e I I 8 plurality of points instead'of at .one point or line. "In the presentinstance, this splitting of the machine is accomplished by omitting one of the tails (Z of one of thelatches 717 which control the hammer action. In the present instance, as clearly shown in-Fig. 6,

it is the sixth latch from the right hand side of the keyboard which is unprovided with a tail (1.

detail, I will state that my invention con-' templates the employment of as many'universal rods or bails 209 as there are sections in the particular split machine and asmany total keys as there are rods or bails 209, so that the series of retainers 415 may be operated in separate groups instead of all together. or in unison. Furthermore, the bell crank .227 is deprived ofone of its functions, that is of controlling the retainers 415, so that its only function is that of controlling the pitman 914 through the medium of the link 911. In the present instance, in which the split machine is one having only two sections, I'provide two special total keys and consequently two special rods or bails 209, although, as is evident, the number of 7 these total keys and bails depends upon the particular number of sections into which the vmachine is split.

Referring now to the present embodiment ofmy invention, the usual bell crank 227 instead of being directly connected with a total key, is an ordinary bell crank whose depending arm which has heretofore been connected with the universal rod or bail 209 is simply of sufiicient length to form an attachment for the spring :1; and whose other arm is operatively connected in the usual manner with the link 91,1; Insteadof having a single universal rod extending from side to side of the machine andoontrolling all of the retainers 415 in unison, I provide two separate and independently operable universal rods marked 209 and 209, as clearly indicated in Fig. 3. The rod 209 is connected by means of the parallel linksor arms ,of the machine. This bell crank is provided at its forward end with a rejecting pin or stud a which projects to the left and intersects theplane of movement of the bell crank 227 It is evident that when the left total key A is depressed the bell crank 227 will be rocked 'in a clockwise direction their corresponding racks 610.

and the pitman 914 put in the (proper position for the taking of a total an that at the same time the bail A will also be rocked in a clockwise direction and the universal rod 209 moved rearwardly, with the result that the retainers 415 belonging to the left hand'section of the machine will be swung to inoperative position. Thus, the racks 610 belonging to such left hand section of the machine are unlocked, whereas all of the racks 610v of the right hand section of the machine will remain in their locked condition. For the purpose of taking a, grand total or "a subtotal of the accumulation in. the left hand section of the machine, the total key A is operated in the same'manner as the usual total key of a Burroughs machine in the taking of a grand total of a sub-total. When the total keyA is released the spring a: restores its bell crank as well as the bail A to normal position.

The other universal rod 209 is, in the present instance, of slightly greater length than the other rod, 209 inasmuch as it accommodat'es or operates five of the retainers 415 instead of four, as in the case of the rod 209,but the mode Iof operation is the same as such latter rod; As herein shown, more particularly in Fig. 3,the universal rod 209 is op eratively'connected by means of the links or arms 216*, with a swinging bail B, which is rovided" with the two similar parallel arms or shaft 204. 'The lower member of the bail B extends from side to side of the machine for the purpose of affordingan operating connection with a special total key 13. This total key B, also marked in the drawing as the Right total forms a part of or is connected to the lower member of the bail B and is mounted to oscillate upon the cross shaft 204. I

Intermediate the length of the upwardly extending arm of the bell crank b which carries the total keyor button B is located a pin or stud b which extends laterally to the left and intersects the plane of movement ofthe upper arm of the bell crank 227", with the result that when such total key or button B is depressed the bell crank 227 rocked in a clockwise direction, for

' the purpose of operating the pitman 914 and placing the same in position for the taking of a total. At the same time the bail B is rocked in-a clockwise direction, with the result that the universal rod 209 is moved rearwardly and the group of five retainers 415 belonging to the right hand section of the machine are rocked to an inoperative position so as to release or unlock Thus, when a which are swung from the transverse rod if the total key B isoperated the racks of the right hand section of the'machine are un.

belonging tothe left, hand section of the machine remain in locked condition. A grand total or a sub-total maybe taken of the. accumulation on the right hand section of the machine by operatingthe right hand total key B} in the same manner as the usual total key off a regular Burroughs machine is operated in thetakingv of such totals. In this manner and by these means I, am enabledto print and list se arate series or sets of items and-to accuniu ate the separate totals atdifferent times so that a total may .be printed of the accumulation of one section of the machine without, at the same time, taking a total of the accumulation of the other section] It is obvious, however,

that if ,it should be desired. to take such totals simultaneously, the same may be accomplished by depressing-both of the two special total keys A and B at the same time which Will cause. the *simultaneous rocking or oscillation of the two bails A and B and the consequent lifting or unlocking of the retainers'415. My invention will be found useful for avariety of different accountant work, for instance it may be conveniently used in a wide machine split at different 1points where it is often desirable to print e total which is accumulated in a particular section of the machine and to then move the carriage before printing the total or totalsv accumulated-imanother section of'the machine.

The spring a which is attached to the bell crank 227': may bemade of sufficient tension to restoreboth of the bails and their universal rods in case either one or both of. them are operated. However, if desired each bailmay be'provi'ded with, its own spring or sp rin s as indicated-in Figs. 1 and 3 wherein the ailB isishown as. provided with light springs w and the other bail of each other.
